Anthropic Tops $1 Trillion in Secondary-Market Valuation, Overtaking OpenAI

Scarce tradable shares on private marketplaces have pushed prices sharply higher.

Overview

  • Anthropic is trading near a $1 trillion implied value on Forge Global, putting it ahead of OpenAI’s roughly $880 billion level on the same private-share platform.
  • These are prices for existing private shares on platforms like Forge Global, not a new funding round, and limited supply can inflate them.
  • Investor demand has been fueled by rapid revenue gains, with Business Insider figures cited at a $39 billion annualized run rate in March 2026, plus strong uptake of Claude Code and deals with Amazon and Palantir.
  • Shareholders report a flood of unsolicited bids, including a $1.05 trillion offer noted by investor Jesse Leimgruber, a $960 billion bid seen by Rainmaker Securities, and even sellers testing $1.15 trillion, with few willing to part with shares.
  • Data from private marketplace Hiive shows Anthropic’s share price up 211% to about $900 over three months as OpenAI rose 8.5% to $608, signaling a shift in investor appetite as traders eye possible IPOs with no dates announced.
